Electronic structure calculations for 2‐D quantum dots and laterally coupled quantum dot molecules in magnetic fields

Abstract

AbstractWe computed the electronic structure of a circular parabolically confined 2‐D quantum dot and a quantum dot molecule in an external magnetic field. The modeled systems are a single six‐electron quantum dot and a quantum dot molecule comprising two one‐electron dots. The calculations were done in real space using current and spin density functional theory. The results are compared to those obtained by the quantum Monte Carlo method. © 2002 Wiley Periodicals, Inc.
